The same writer continues as follows: "Even as it is man is able to perceive only a limited number of sound vibrations--there are many sound vibrations above and below his scale, and which he is unable to perceive, but which are registered by delicate instruments. Likewise, man is able to perceive only a limited range of light vibrations, there being enormous fields of such vibrations above and below his range. Again, man is unable to sense electrical waves, or magnetic waves--though, theoretically, he should be able to sense these as well as light waves, the difference between these respective fields of etheric vibrations being simply different rates of vibration. Imagine what a new world would be opened to man if he could sense the waves of electricity. In that case he could 'see' things as far away from him as the waves of electricity could travel, and even though solid objects intervened, as in the case of the X-Rays. In such a case a man might actually 'see' things at the other side of the world, by means of 'wireless electrical waves.' Theoretically these things are possible, providing that man's optical nerves are rendered more sensitive, or provided that he evolves a new set of sensory nerves and instruments of impression." Discovery of New Worlds. Another psychologist says: "If a new sense or two were added to the present normal number in man, that which is now the phenomenal world for all of us might, for all that we know, burst into something amazingly different and wider, in consequence of the additional revelations of these new senses." Another authority has said: "It does not seem at all improbable that there are properties of matter of which none of our senses can take immediate cognizance, and which other beings might be able to see in the same manner that we are sensible to light, sound, etc." Another writer has said: "We know that our sensory nerves are capable of transmitting to the brain only a part of the phenomena of the universe. Our senses give us only a section of the world's phenomena. Our senses usher only certain phenomena into the presence of our minds. If we had three or four new senses added, this might appear like a new world to us; we might become conscious of a vast number of phenomena which at present never have any effect upon our nervous system. It is not possible to imagine a race of beings whose senses do not resemble ours, inhabiting other worlds." Transcendental Senses
